After spending their first year of high school in peace and quiet, Haruka and Makoto run into Nagisa, a new student who was a member at a swimming club with them when they were kids.  That swimming club is being torn down, so the three of them sneak in to dig up a time capsule that they buried in the back, which is when they are reunited with Rin, the fourth member of their group who left to study abroad.
Don't call me Gou. Everybody calls me Kou.
Nenn mich nicht Gou. 
Alle nennen mich Kou.
No me llames Gou. A mí me dicen Kou.
No me llames Gou, que le he dicho 
a todo el mundo que me llame Kou.
Ne m’appelle pas Gou !
Non chiamarmi Gou. Tutti mi chiamano Kou.
Não me chame de Gou. Eu peço pra 
todo mundo me chamar de Kou.
Не зови меня Го. Все называют меня Ко.
